Abstract: 본 발명은 엔진에서 발생되는 2차기진력을 모멘트평형으로 제거하기 위한 것으로, 엔진(10)에 일체로 부착되며 기진력이 없는 변속기(11)의 중량을 고려하여 피스턴에서 발생되는 모멘트의 총합(∑M E )과 반대방향의 모멘트(M B )가 발생되도록 설치된 밸런스축(20)의 모멘트가 상쇄되는 것을 특징으로 하는 자동차 파워트레인의 2차밸런서이다.

Abstract: 완충된 수성산성 세정 조성물은 pK a 2-3.5의 약산과 그 짝염을 조성물 전체 중량의 3-10 범위로 포함하고 있고 약산과 짝염은 짝염에 대한 약산의 몰농도 비율이 1:30 내지 30:1이 되도록 포함되었으며 최종 조성물의 pH는 2-3.5로 되었음. 이 조성물에는 조성물을 점탄성으로 만드는 겔화제시스템과 방향제, 착색제, 유기용제, 살균제, 표백제 등의 기타성분이 첨가될 수 있음. 약산으로는 구연산이 적당하고 겔화 시스템으로는 세틸 트리메틸암모늄클로라이드와 나트륨 크실렌설폰네이트 또는 알킬디페닐에테르 설폰네이트를 함께 사용하는 것이 바람직함. 조성물의 점도는 계면활성제/카운터이온의 농도 및 중량비에 의하여 조정될 수 있음. 이 조성물에 의하면 산성 세정활성이 우수하고 분무시 힘이 들지 않으면서 손이 닿지 아니하는 세정할 표면에도 조성물이 묻도록 쉽게 처리할 수 있음.

Title: Ink-jet recording method and its apparatus
Inventor: NAGOSI SIGEYAS
IPC: H04N1/12
Filed: 1993-12-03
Granted: 1998-04-23
Abstract: An ink jet recording apparatus performs the recording, using a recording head for discharging the ink onto the recording medium to effect the recording, while moving said recording head in a main scan direction. The recording head has a plurality of discharge orifice groups in the main scan direction, each of which has a plurality of discharge orifices for discharging the inks of different colors provided in a direction different from the main scan direction. A predetermined image data is divided into thinned image data, which is in complementary relation to each other, each of the thinned image data being supplied to a different discharge orifice group, so that predetermined image data can be recorded using different discharge orifice groups. The occurence of deviation and unevenness of the printed image can be prevented. <IMAGE>

Title: Operational amp circuit
Inventor: SONG WON-CHOL
IPC: H03F3/183
Filed: 1993-12-11
Granted: 1996-06-20
Abstract: a main operational amplifier(10) for generating a differential output signal by charging and discharging two capacitors(C1, C2) of an output terminal with a supply voltage(Vdd) responding to a differential input signal; an auxiliary operational amplifier(20) for generating a monitor signal to show a operating mode of the main amplifier; and a transconductor(30) for increasing a slew rate by being turned off when the monitoring signal indicates a small signal mode, or by supplying predetermined current(I19) to the main operational amplifier when a monitoring signal indicates a large signal mode; thereby achieving a high speed operational amplifier.
